Assert that a large enumerable contains only the very same item n times?
See original GitHub issueI have a collection of 100K sample numbers. In one test case I want to assert that all of them are of the same value. I tried:
values.Should().AllBeEquivalentTo(5);
This takes quite some time (around five seconds). Which is WAY to long. Is this a bug in the implementation? Why is it taking so long? I think it’s the wrong function, but I couldn’t find a .AllBe(5) for which I was looking for originally.
My workaround now is values.Distinct().Should().BeEquivalentTo(new[]{5}); but I don’t like it because it doesn’t express my intent.
Ideas on how to do that properly?

@drauch Forget my last comment, I was looking at the wrong test after all. I confirm that execution time gets excessively long for larger collections.
